WIND AND SOLAR ENERGY, CONTRIBUTING 14% ALL ELECTRICITY IN THE U.S. LAST YEAR. >> WELL, TENSIONS ARE ALSO RUNNING HIGH IN COURT FOR GWYNETH PALTROW AND THAT SKI ACCIDENT TRIAL. SHE'S INVOLVED WITH PALTROW AND HER ACCUSER, TERRY ANDERSON, HAVE NOW TAKEN THE STAND, BOTH TELLING VERY DIFFERENT STORIES ABOUT THE INCIDENT IN QUESTION. TODAY, THE COURT WILL HEAR FROM AN EXPERT IN THE BIOMECHANICS OF SKIING AS WE WAIT TO SEE IF PALTROW WILL ACTUALLY TESTIFY AGAIN, ABC NEWS LEGAL CONTRIBUTOR AND CRIMINAL DEFENSE ATTORNEY SEAN ALLOYED JOINING ME NOW. SO, SHANNA, AT THIS POINT SEEMS LIKE A BATTLE OF THE EXPERTS. ABSOLUTELY. HERE WE HAVE THE EXPERTS FROM THE PLAINTIFF'S SIDE, EXPERTS FROM THE DEFENSE SIDE, AND THEY'RE EACH GOING TO TESTIFY TO THE THINGS THAT THEY BELIEVE, A TRIBUTE TO THEIR VERSION OF WHAT HAPPENED THAT DAY AND HOW IT'S SUPPORTED THROUGH SCIENCE AND MATH. >> SO YESTERDAY, WAS THE FIRST TIME THAT SANDERSON AND PALTROW WERE ACTUALLY IN THE COURTROOM TOGETHER FOR THE WHOLE DAY. WHAT DID YOU MAKE OF BOTH OF THEIR TESTIMONIES AND DID ANYTHING STAND OUT TO YOU? >> WELL, WHEN WE LISTEN TO EACH OF THE TESTIMONIES, EACH OF THEM REALLY TRIED TO CONVEY WHAT HAPPENED IN THEIR OPINION. THAT PARTICULAR DAY, GWENETH TOOK THE STAND. SHE WAS VERY CLEAR , CONCISE. SHE WENT OVER THE SAME POINTS. SHE DIDN'T ALLOW THE PLAINTIFF ATTORNEY TO RUFFLE HER IN ANY WAY, WHICH IS ALWAYS IMPORTANT BECAUSE WE WANT A JURY TO SEE A VERY CALM, COOL, COLLECTED WITNESS WHEN WE TALK ABOUT SANDERSONS TESTIMONY, WE SAW HIM BE MOMENTS WHERE HE DISPLAYED THE SIGNS OF THESE SORT OF EFFECTS OF THIS TRAUMATIC BRAIN INJURY THAT HE CLAIMS HE'S SUFFERING FROM. HE RECOUNTED A DISTRESS THAT HE FELT, HOW HE FELT THREATENED. SO HE GOT HIS POINTS ACROSS IN THE TESTIMONY TO THE JURY BECAUSE EACH SIDE WANTS TO BE SURE TO CONNECT WITH THE JURY AND THEY WANT TO COME ACROSS AS BELIEVABLE. SO THIS MAN, SANDERSON, IS ASKING FOR THREE HUNDRED THOUSAND DOLLARS CLAIM WAS OUT OF CONTROL, SKIING CAUSED FOUR BROKEN RIBS, PAIN SUFFERING, PERMANENT TRAUMATIC BRAIN INJURY. PALTROW IS COUNTERSUING FOR ONE DOLLAR. CLEARLY, THAT ONE DOLLAR IS SYMBOLIC HERE. WHAT DO YOU MAKE OF THAT? YOU KNOW, THIS IS A REAL COURT CASE, BUT IS THIS NECESSARY? >> ABSOLUTELY. WHAT SANDERSON WAS SEEKING ORIGINALLY WERE MILLIONS OF DOLLARS. BUT THE JUDGE STRUCK DOWN THE PUNITIVE DAMAGES, WHICH BROUGHT HIS RECOVERY VALUE DOWN SIGNIFICANTLY. WHAT HE'S LOOKING TO RECOVER ARE WHAT HE CONSIDERS HIS PAIN AND SUFFERING FOR HER ACTS. HE'S ALSO LOOKING TO GET BACK HIS MEDICAL BILLS AND BE REIMBURSED FOR THOSE COSTS THAT HE BELIEVES ARE ATTRIBUTED DIRECTLY TO THE ACCIDENT. WHEN WE LOOK AT WHAT MISS PALTROW IS TRYING TO RETRIEVE, SHE'S DOING THE DOLLAR IN A SYMBOLIC ACT TO SAY THIS IS MORE ABOUT REPUTATION THAN IT IS FINANCIAL GAIN. >> IN HER PARTICULAR INSTANCE, DO YOU I MEAN, WHAT DO YOU MAKE? LOOK, WE COVER THESE COURT CASES. MANY TIMES BECAUSE OF, YOU KNOW, THE SUPERSTARS WITHIN THEM. RIGHT. IS THIS SOMETHING I MEAN, HOW DO YOU FEEL ABOUT THE FACT THAT THIS IS GETTING SO MUCH COVERAGE AND IS THERE SOMETHING THAT WE ALL CAN LEARN FROM THIS ? OR IS THIS CLEARLY ALL ATTENTION ON THE MOVIE? STAR HERE? >> ABSOLUTELY. I MEAN, WHEN WE LOOK AT A CASE LIKE THIS, THIS IS A SKIING ACCIDENT. IT'S A HE SAID SHE SAID THIS IS NOT THE TYPE OF LEGAL CASE THAT NORMALLY IS GOING TO GARNISH ANY SORT OF SECOND LOOK FROM THE LEGAL COMMUNITY. THIS IS DEFINITELY A TRIAL THAT'S RECEIVING THIS LEVEL OF ATTENTION BECAUSE SHE IS A CELEBRITY. AND SO SHE'S GETTING A LOT OF ATTENTION DUE TO THE FACT THAT THIS CASE HAS DRAGGED ON SO LONG. AND IT'S SHE IS ONE OF THE PERSONS WHO ARE OF INTEREST. AND SO THAT'S REALLY WHY WE'RE GARNISHING THE ATTENTION IN THIS PARTICULAR CASE. BUT, YOU KNOW, THE LARGER IMAGE AND THE LARGER PICTURE IS , IS THAT LEGALLY WE ARE ALL RESPONSIBLE FOR OUR ACTS. AND SO WE DO HAVE TO ABIDE BY CERTAIN IN THIS PARTICULAR CASE, THE SKIING'S CODE, BECAUSE YOU CAN BE FOUND NEGLIGENT IF YOU ARE NOT ABIDING BY THESE TYPES OF STATUTES. >> ALL RIGHT. >> STAY TUNED.
